Gain and Tone controls do not work in my Kliche mini! Help!!!

[OscarA2B]

I really don’t know what else to do with this pedal, the volume is low, the Gain and Tone control don’t seem to make any difference! I have tried to replace the ICs, checked all the parts individually, replaced some resistors but still nothing happened!

I replaced the Jacks just in case as well, the bypass works good but when I engage the pedal, I have to roll all the volume pot all the way up to get some volume but that is it, not gain or tone changes!!

Any one could help me with it please?

i'm not familiar with those particular jacks... so i'm no help there... I do see some of your soldering isn't wicking to both sides... you could have a cold joint.... unbox it and go ahead and touch up your joints.... and does your led work?

I just reheated the joint but still the pedal is doing the same!!

@OscarA2B I would test the controls outside the enclosure. Make sure the pots are not shorting on any solder pads. I don't see a dust cover or electrical tape on your tone control.

Yes, I do have electrical tape under the tone control, just removed it to take the pic so the soldering could be visible!

I dont get why I still have a little amount of volume but nothing else happens.

wait... what's with the wires coming off the dual gang? is that a single gang and you have wires doubled up? and do you have back of treble pot insulated with a dust cover?

electrical tape is not a good idea... the leads can just poke through and short..... hook up power to pcb outside the enclosure.. bend the treble pot off the board and test for signal with all controls

I know you said you checked your parts, but I’d do another pass looking for a multiplier error on a resistor somewhere - 470k that should have been 47k etc. that would be my first guess for what would cause your problem.

On future builds, there is an advantage to sticking to one resistor type and facing them all the same way. Makes reading the color bands much easier when you’re troubleshooting.
